Abstract

The invention discloses a vertical adjustable variable wind face blade for a wind driven generator. The vertical adjustable variable wind face blade comprises a blade fixing device, a main blade, an auxiliary blade, guide rail grooves, a screw rod, a screw rod terminal fixing device and a wind sensor. Lugs are arranged at the bottom of the auxiliary blade. The screw rod is arranged on the main blade. A controller and a screw rod total segment fixator are arranged on the two sides of the left side of the screw rod correspondingly. The upper side and the lower side of the screw rod are both provided with the guide rail grooves. The main blade is connected with the auxiliary blade, and the auxiliary blade is arranged at the top of the main blade. The guide rail grooves in the main blade are connected with the lugs on the auxiliary blade. The auxiliary blade is provided with the wind sensor. In this way, the wind area of the vertical adjustable variable wind face blade can be changed according to the magnitude of wind power, the adaptive range of the wind driven generator to wind speed is widened, the arm of force is reduced while the wind face is reduced, and the load of the blade joint is lowered.

Description

technical field [0001] The invention relates to energy fields such as wind power generators, in particular to a vertically adjustable variable wind surface blade of a wind power generator. Background technique [0002] As an important form of clean energy, wind power is attracting more and more attention. In order to make the generator have a relatively stable working state under different wind forces, changing the wind-receiving area of ​​the blades has become an effective solution. The existing method is mainly to change the wind-receiving area of ​​the blade by rotating the blade, but it cannot change the wind-receiving area of ​​the blade through the wind degree. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a vertically adjustable variable wind surface blade of a wind power generator, which has the advantages of wide adaptability and high adjustment efficiency. [0004] In order to solve the above techn...
